ABSTRACT:
The vane structure fits within a side opening of an aircraft jet engine normally covered by a pivoted clam shell arrangement. When the clam shell arrangement is actuated, it swings from the side opening in a direction to intercept thrust gases normally passing rearwardly of the engine and direct the gases laterally out of the side opening, the vane structure directing the gases upwardly and forwardly to provide a reverse thrust. The vane structure itself includes a number of beams lying in parallel vertical planes and a number of vanes in the form of continuous strips extending transversely to the direction of the beams, the beams having slots through which the vanes pass to define an egg crate like interlocked grid structure. The vanes are tilted forwardly slightly relative to the vertical to provide the forward component of gas movement creating the reverse thrust.
